Abstract
This paper discrives the analysis and evaluation of sound from waterflows. The experimental waterflows containing the step are setup in the Anechoic Chamber and the sounds from the water step flow are recorded in DAT. Then the sounds are analysised by Sound Valuation System. The Sense experiments evaluated by healing examinations are put into practice and the propriety of Sound Valuation System is considered. Finally, the comfortablity of waterflows sounds is cleared and the analysis methods of them are established.
